The Government has released the terms of reference for its special select committee to review the Emissions Trading Scheme.
Under National's post-election deal with ACT, the committee is to take another look at the scheme. National says the legislation rushed through by the Labour-led Government.
The committee, to be chaired by United Future leader Peter Dunne, will examine the relative merits of an emissions trading scheme or a carbon tax, and how the options might affect international relations.
Former climate change minister David Parker, Green Party co-leader Jeanette Fitzsimons and ACT leader, Rodney Hide are also on the committee.
The weakened state of the economy is to be taken into account when deciding on climate change measures.
The Government confirmed on Tuesday that the science of climate change will also be looked at as part of the select committee review.
Earlier in the day when National released the terms of reference, it left that point off the Parliamentary Order Paper, due to what it called an administrative error.
Academics and the Green Party say the review of climate change science will make New Zealand the laughing stock of the international science community, and will damage the country's credibility in international climate change negotiations.
Prime Minister John Key has said he wants the committee to have considered its work and taken submissions in time for legislation to be passed by the end of September 2009.
